Maybe it means 'conforming to the environment around you', like a water bed moves around to accomodate whoever lies on it. It is resiliant! Possibly too it might mean not being too firm and rigid, living life in a box, as it were, but rather being fluid--ble to adapt easily which goes back to my first interpreatation! Well, never heard that one before! LOL.

So, what would it mean if someone said, "When i grow up I want to be high heels!" You could have some fun with this, and make up things to say to people....but maybe insert, "When I get old".....
